Researchers have found that ginger eases nausea and vomiting caused by motion sickness, morning sickness, surgery and chemotherapy.

In one study of 80 new sailors who were prone to motion sickness, those who took powdered ginger had less vomiting and cold sweats than those who took a placebo, said the University of Maryland’s Center for Integrative Medicine.

Natural pain relief:

Ginger can reduce symptoms of menstrual pain, according to the U.S. National Library of Medicine. One study showed that taking a ginger extract at the beginning of the menstrual period reduced pain symptoms in 62 per cent of women.

A study at the University of Sydney found that the active ingredients in ginger directly affected pain pathways and recduced inflammation.

Ginger extract showed “significant antidepressant activity” in a study that was published in the International Research Journal of Pharmacy.

Anti-inflammatory:

Studies show that ginger inhibits several genes that contribute to inflammation, which causes or contributes to a range of health problems including cardiovascular disease, obesity and Alzheimer’s disease.

Antibiotic:

Ginger was more effective than antibiotic drugs in fighting two bacterial staph infections, according to a study published in the Journal of Microbiology and Antimicrobials.

Cold and flu prevention and treatment:

Ginger contains almost a dozen anti-viral compounds and scientists have identified several that can fight the most common cold virus, the rhinoviruses. Other compounds in ginger - gingerols and shogaols - help relieve cold symptoms because they reduce pain and fever and suppress coughing.

Aids digestion:

“Stomach acid is crucial to human digestion and when we’re stressed its production can break down. Ginger stimulates the taste buds, triggering digestive secretions,” said Mackintosh.

“Hot water with a slice of lemon and chopped ginger is an excellent way to stimulate digestion.”

A study published in the European Journal of Gastroenterology and Hepatology found that ginger stimulates digestion by speeding up the movement of food from the stomach.

Fights diabetes:

Ginger can help to manage blood sugar levels in long-term diabetic patients, according to research conducted recently at Sydney University.

Professor of pharmaceutical chemistry Basil Roufogalis, who led a study that was published in the natural health journal Planta Medica, said ginger extracts increased the uptake of glucose into muscle cells independently of insulin.

Choose fresh ginger root over the dried form - it tastes better and has higher levels of gingerol and anti-inflammatory compounds. Unpeeled ginger can be stored for up to three weeks in the fridge and up to six months in the freezer.

Adults should not eat more than four grams of ginger per day and pregnant woman should limit their intake to one gram a day, according to the University of Maryland Medical Center. Ginger should not be given to children under two, it said.

Ginger tea is, of course, widely available in stores but this home-made fresh ginger tea takes only a minute or two:

Peel a small section of a fresh ginger root, grate about a quarter of a teaspoon into a cup, add boiling water and a sweetener of your choice.
